I've tried to test suspend with diff I posted [1], but I did it only on dra7 and am43 where suspend i more simple than on omap3. Also, I worry that with such approach some irq can be missed (especially edge ones), because PRCM irqs will be re-enabled at very late resume stage (right before thaw). Second option, I see, is to rework PRCM to be threaded IRQ, but in this case all children IRQs will need to be threaded/nested threaded (including PCS, legacy OMAP mux, OMAP3 _prcm_int_handle_wakeup/_prcm_int_handle_io). Are there any objection to convert PCS to threaded IRQ, for example? ;) [1] https://patchwork.ozlabs.org/patch/578915/ -- regards, -grygorii -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
